Government workers, along with school employees and students, headed home around the same time Monday afternoon, leading to massive traffic jams throughout much of the metro, therefore slowing snowplows down.

“The overnight time really gives us a chance to catch up,” said OKC spokeswoman Kristy Yager.

Thirty snowplows will be in use Monday night to clear remaining snow and drop salt to fight ice on snow route roads.

“We’ve driven every snow route already at least once, twice, maybe three times, so we should have hit every street,” Yager said.

Snowplow drivers will switch out at midnight and again at noon Tuesday. Maintenance crews also are working overtime in case any snowplow needs repairs.

“We do see the temperatures coming up to the mid-40s (Tuesday), and that’ll be our best friend,” Yager said.
